Police identified the man Wednesday as Todd Keeling, 48, of White Bear Lake, Minn. According to Cobb County officer Sarah O'Hara, Keeling was a third-party contractor and was found by a fellow worker.

"He was there just doing his job," she said.

The stadium, home to the Braves, opened last season.

O'Hara declined to say if foul play was suspected in the death.

"This is still an active investigation," O'Hara said, adding police were waiting for an autopsy report. "From there they'll decide if it's a homicide or accidental suicide. There's many avenues it could go, but at this time, we're just gathering information."

O'Hara said the Braves are cooperating with the investigation.

The Braves game against the Reds on Tuesday at SunTrust Park began as scheduled at 7:35 p.m. ET.
